Firm ownership and the macroeconomics of incentive leakages

Questions about market power have become salient in macroeconomics. We consider the role of institutional structures in addressing these within a dynamic general equilibrium framework. Standard models account for monopoly profits as a lump-sum transfer to the representative agent. We label this an "incentive leakage," and show this to be a general characteristic of firm-optimal arrangements. We show that shareholder-operated or worker-operated firms that eliminate leakage can generate within-firm incentives that effectively reduce monopoly distortion in equilibrium. When all firms operate similarly, an additional general equilibrium effect arises through internalization of an aggregate demand externality. We characterize steady-state welfare across structures, and show how zero-leakage institutions lead to improvements towards the Golden Rule benchmark. Overall, our paper takes the first step towards an analysis of the macroeconomics of institutions without incentive leakage. JEL Classification: E10, E22, E24, E25
